Unbilled Gewährleistungs-Reparaturen und verlorene Rückgriffsforderungen gegen Nachunternehmer
Definition
Defect management breakdown creates revenue leakage: (1) Defect discovered but not formally documented, (2) Rework ordered but not tracked as recoverable, (3) Subcontractor's liability period expires before claim is issued, (4) Contractor absorbs cost as 'goodwill' or margin erosion, (5) No credit note or contra-invoice issued. The financial loss is hidden in project profit margin or written off ad hoc.
Key Findings
- Financial Impact: €1,000–€20,000 per unrecovered defect × 5–10 incidents/project/year = €50,000–€200,000 annual leakage for mid-sized contractor. Conservative estimate: 5–10% of warranty-related rework costs never recovered.
- Frequency: Per defect; occurring throughout warranty period (highest risk after 3–5 years when memory fades).
- Root Cause: Manual systems don't enforce defect-to-recovery workflow. Rework is executed based on verbal instruction, no formal cost tracking. Statute of limitations (§634a BGB = 5 years) expires before claim is formalized.
